9 claims. 1m29- 14) meat, food, medicine, beverages or other items whichmust be kept cool, are often needed for Vstoring and cooling such items.Since such containers are often transported from place to place, as whenused to carry beverages for consumption at picnic outings, shipping lishor fowl or transporting medicines, and the like, the containers shouldbe light in weight so that they may be easily portable and adapted toair transport. Furthermore, since they may be subjected to roughhandling they should be rugged in construction and capable of beinglocked closed. They should also lend themselves to stacking. Moreover,since the articles may be stored in the containers for prolonged periodsof time before being used, the construction of the containers must be'such that the passage of heat into the interior of the containers is atan exceedingly slow rate so that the rate of melting of the ice whichcools the contents will be as slow vas possible. Containers presentlyused for containing ice for cooling articles stored in the containersare made of metal and are, therefore, very heavy. In addition, theircost of manufacture is relatively high.

It is desirable, therefore, that a container be provided which is strongbut relatively light in weight which will hold ice for prolonged periodsof time, 'and which may be easily and economically manufactured, andsuch are objects of this invention.

lt is also an object of this invention to provide a new and improvedcontainer made of paper board or the .like

for containing ice to cool articles stored in the container.

A further object of the invention is to provide a container of theYcharacter described which may be assembled from a plurality of easilyassembled knocked down parts, so that the parts may be shipped in atknocked down condition and may be erected and assembled at the point ofuse.

Another object of the invention is to provide a carton for containingice made of corrugated paper board and having spaced air insulatingchambers for preventing the passage of heat into the interior of thecarton.

Still another object of the invention is to provide a new and improvedpaper board carton having spaced inner and outer walls providinginsulating air chambers therebetween.

A particularly important object of the invention is to provide a new andimproved carton in which a moisture impervious paper board or like tankis disposed in a cardboard container, the container and the tank havingflaps which space the walls of the tank from the Walls of the containerto provide heat insulating air spaces or chambers therebetween.

Additional objects and advantages of the invention will be readilyapparent from the reading of the following ICC 2,766,921

description of a device constructed in accordance with theinventi'on andreference to the accompanying drawings thereof, wherein:

Figure 1 is fa perspective view of a container, constructed inaccordance with the invention, for containing ice to cool articlesstored in the container,

Figure 2 is a vertical sectional view of the container taken on the line2 2 of Figure l,

. Figure 3 -is "a vertical sectional view 'of 'the 'container takenonthe line 3-3 of Figure 2,

Figure 4 is a bottom plan View of the container,

Figure 'Sis a perspective view of the container with the top removed andwith Vportions of the container broken away toshow the tank in position,

Eigure 6 is a perspective view of the moisture impervious tank, and

vFigure 7 is a'plan view of a blank for forming the outer container.

In the drawings, the numeral It? designates a container which isprovided with a cover 11 and a moisture impervious tank 12. Thecontainer 10 is formed of a blank 13 cut from a sheet of material,preferably cardboard or the like, perforated and scored and ready forassembly. As clearly vshown in Figure 7, the Vcontainer blank vis scoredto provide a back wall panel '14, an adjacent end `wall panel 15, afront wall panel 16 substantially identical in size with the b'ack sideWall panel 14, a second end wall panel A17 adjacent the front wallpanel, and a ap 18. The various wall panels are outlined by verticalimperforate scored lines .19 which provide for ready folding of thecontainer blank into the rectangular form shown 'in Figures l, 4 and 6,whereby the flap 18 may be secured by staples 26, 'or in any othersuitable manner, to the inner surface 'of the back wall panel 14 to formthe rectangular walls of the container 10.

Integral bottom closure portions 21 and 22 are formed integral with theback and front wall panels 14 and 16, respectively, and are dened by theimperforate scored fold lines 23 and 24, respectively. The upper bottomclosure portion 21 overlies the lower bottom closure 22 (Figures 2 and3). A pair of opposed bottom closure aps -25 and 26 are formed integralwith the end wall panels 15 and 17, respectively, and are defined by thetransverse imperforate scored lines 27 and 28, respectively. The bottomclosure llaps 25 and 26 are provided with reduced or narrowed endportions 29 and 30, respectively, which are adapted to pass through theperforation or slot 31 in the lower bottom closure portion 22. Thereduced end portions 29 and 30 are ea'ch provided with a pair ofimperforate scored fold lines 32 which enable the reduced end portionsto bebent up and through the slot 31 and'then down to lie between theupper and lower bottom closure portions 21 and 22, as clearly shown inFgure- 2. It will be evident that when the upper bottom closure 'portion21 is folded down to abut the reduced end portions, the end portions areheld fast thereby, and the bottom structure is positively locked inerected position. It will also be evident that the reduced end portionsspace the upper and lower bottom closure portions from each other toform an air space or chamber 33 therebetween.

Upper rectangular flanges 34, 35, 36 and 37 are formed integral-*withthe Wall panels 14, 15, 16 and 17, respectively, and are dened by thetransverse imperforate scoredfold lines 38, 39, 40 and 41, respectively.The

Aupper anges 34, 35, 36 and 37 are provided with fold lines 42 whichpermit the horizontal portions 43, 44, 45 and 46, respectively, tooverlie the upper edges of a rectangular liner having walls 47, 4S, 49and 5% disposed in the container 10 contiguous to the front, back andend wall panels of the container. The flanges are bent downwardly andinwardly to overlie the upper ends of the liner walls. The liner walls47 to 50 may be integral l Patented Oct. 16,

Y tank.

and cut from a sheet of material, preferably cardboard or n the like,and scored to allow Vthe walls 47 to 50 to be disposed into a roughlyrectangular shape to form the liner.

it will be apparent now'that the rectangular upper flanges will retainthe liner wallsY in position and that the lower ends of the liner wallsin lturn will prevent the upper bottom closure portion 21 from beingbent upwardly to tree the reduced end portions 29 and 30 of "the bottomclosure laps 25 and 26.

A pair of elongate tongue members 51 andr52 may be cut outor orm'edinthe end wallV panels 15 and 17, Y respectively, `such tongue membersextending to the fold lines 42 of the upper flanges 35 and 37. Thetongue members vare-adapted to extend upwardly through 'slots 53 and y54.in the cover 11, then'berbent downwardly around the outer end flanges55 and 56 of the cover so that the -tree end portions of -the tonguesmay be 'disposed between the cover anges and the Vend wall 62 and a backwall 63. The front wall 62 is connected to the side Vwalls 61 and 62 bythe folded triangular flap vportions 64 'and 65, and the back wall 63 isconnected by'fsilnilary l'lap portions 67 68 to such side Walls.

The 'front wall 62 is provided withfa retaining flange 66 and the backwall with a llange v69 which fold outwardly and then downwardly over theupper portions of the triangular flap portionsto retain them in theirVfolded positions, the tank ilange 66 being l'disposed adjacent andabutting the container ii-ange 36 and the tank flange 69 adjacent landabutting the container ange 34 when the tankV is inserted into thecontainer.

It will be seen now that the container anges 35 and 37V space the `endwalls 60 'and 61 of the -tank from the liner walls 43 andv 50,respectively, so that heat insulating air spaces or chambers 70 :and 7K1are formed therebetween. Similarly, the -tanky ange 66 vand thecontainer ange 36 space the -front wall 62 of the tank from'the linerVwall 49, and the tank ange 69 and the container flange 34 space the tankrear wall 63 from the liner wall 47 Vto form the heatrinsulatin'g airspaces or chambers 72 and 73, respectively. The lfour sides and thebottom of the tank being surrounded by the air chambers 33, 70, 71, 72and 73, in which the air is, of course, substantially at rest, theair'chambers insulate the tank and reduce iiow of heat into the tank tomelt the ice which may be contained in the tank.

and lthen inwardly and upwardly inside the cover flanges v A rectangularmoisture impervious cover plate 74 running along the front and backwalls of the tank and container. The cover 11, of course, ioverlies thecover Vplate 74 and Vholds it in place, the tank being of such Yheightthat the coverV plate Yis disposed between the liner walls and betweenthe cover and the anges 66 and 69 and the upper edges of the end walls60 61 of the If desired, a layer of foil metal, such as aluminum or Vtinlfoil, may be provided to cover the inner surfaces of l tively broad,iirm supporting surfaces for the cover plate the tank 12 to provide-moisture imperviousness and in-V `creased insulating value to the tank.

The container may be easily assembled by.V bending the Wall panels 14,15, 16 iand 17 in rectangular form and then `stapling the panel diap 18to the rear wall panel 14. The upper bottom closure 21 is bent inwardlybetween the wall panels and then the lowerrbottom closure 22 is bentperpendicular to the wall panels. The bottom closure flaps 25 and 26 arethen bent inwardly 'and their reduced end portions 29 and 30 are passedthrough the slot 31 and bent downwardlyto lie over the lower bottomclosure 22. The upper bottom closure is then moved into parallelrelationship with the lower bottom closure portion 22 and over thereduced end port-ionsy of the closure flaps. The liner with its walls47, 48, 49 Iand 50V is then insertedY into 'thecontainer and the anges34, 35, 36 and 37 are bent over and down over the upper portions lof theliner walls. The

tank 12 is then placed in the container, ice 'and lthe articles to becooled are placed in the tank,V the moisture- Vproo'ted cover, 74 Visplaced over the tank, and iinally 'the Y `cover 11 isY placed inposition on the container, the tongue members 51 and 52 being foldedaround thecover flangesltohold the cover 11 on the container.H f

It will thus be seen that a container for holding ice and articles to becooled has been provided which is made of cardboard or the like, and iseasily assembled from a plurality of scored blanks which lform acontainer 10, liner walls, and a moisture-proof tank 12. It will also|be seen that the container is light in weight but of strong, ruggedconstruction', the liner walls rein-forcing the container, and that thecontents of the tank :are well insulated by means of the air chambersbeneath and on the sides of the tank which minimize the passage of heatfrom without the container into the tank.
